My research interests concern the behavioral and chemical ecology of social caterpillars. Much of my work has involved tent caterpillars but more recently I have been studying social species occurring in Mexico, Costa Rica, and Spain. I maintain a website on the behavioral ecology of social caterpillars.
|I particularly encourage students interested in behavior and ecology to work in my laboratory. Over the summer I usually have several students conducting laboratory and field studies. A number of my technical papers have been co-authored with undergraduates.|
